i.MX8MN has similar architecture with i.MX8MM, so it could reuse
the clock code of i.MX8MM, but i.MX8MN has different CCM root
configurations, so need a separate root entry.

The power domain tree is not accepted by Linux Kernel upstream.
only a single pd node is used currently, as following:
pd: imx8qx-pd {
compatible = "fsl,imx8qm-scu-pd", "fsl,scu-pd";
#power-domain-cells = <1>;
};
So to migrate to use upstream linux dts, we also need a driver
to support this.
This patch is to support the new method, compared with legacy power
domain tree, it will be simpiler, because each device will
has resource id as power domain index, it will be directly passed
to scfw, and no need to let power domain build that tree. If multiple
power domain is needed, it is the dts node should has correctly power
domains entry added and sequence correct.

The current i.MX8 power domain driver is based on i.MX vendor
power domain tree which will retire later.
The Linux upstream use a single pd node for power domain driver,
and U-Boot will adopt that. When U-Boot i.MX8 dts synced with
Linux Kernel upstream and related driver ready, the legacy
driver will be removed.

clk and pinctrl will be get(probed) during each device probe,
we don't need to probe them in scu driver. Only need to bind the sub-nodes
(clk and iomuxc) of MU node with their drivers.
So drop the code to probe the clk/pinctrl, and this patch will make it
easy to add more subnodes.

During mmc initialization, there are several calls to mmc_set_clock
and mmc_set_ios. When mmc_power_off, the mmc->clock will be set,
but the imx driver will use 400KHz. So the following calls
to mmc_set_ios will set the clock several times which is redundant
in fsl_esdhc_imx driver. So let's simplify to remove redundant
clock settings.

This patch is to clean up bus width setting code.
- For DM_MMC, remove getting "bus-width" from device tree.
This has been done in mmc_of_parse().
- For non-DM_MMC, move bus width configuration from fsl_esdhc_init()
to fsl_esdhc_initialize() which is non-DM_MMC specific.
And fix up bus width configuration to support only 1-bit, 4-bit,
or 8-bit. Keep using 8-bit if it's not set because many platforms
use driver without providing max bus width.
- Remove bus_width member from fsl_esdhc_priv structure.

When preparing to possible expand or contract an entry we reset the size

At present all the 'command' methods return bytes. Most of the time we
actually want strings, so change this. We still need to keep the internal
representation as bytes since otherwise unicode strings might break over
a read() boundary (e.g. 4KB), causing errors. But we can convert the end
result to strings.
Add a 'binary' parameter to cover the few cases where bytes are needed.

For better or worse libfdt recent grew a lot of code that checks the
validity of the device tree in great detail. When using unsigned or

Add some controls to select the trade-off between safety and code size.

Unfortunately libfdt needs this value now, which is present in the

of constants appear in the linux/kernel.h header instead.
